A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle.

[2] The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors. However, other mechanisms to capture and use energy are included.
An electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in batteries or another energy storage device. Electric motors give electric cars instant torque, creating strong and smooth acceleration.
The BMW M3 is a high-performance version of the BMW 3-Series, developed by BMW’s in-house motorsport division, BMW M.

M3 models have been derived from the E30, E36, E46, E90/E92/E93, and F30 3-series, and sold with coupe, saloon and convertible body styles. Upgrades over the “standard” 3-Series automobiles include more powerful and responsive engines, improved handling/suspension/braking systems, aerodynamic body enhancements, and interior/exterior accents with the tri-colour “M” (Motorsport) emblem.

The last M3 coupe was produced in Germany on 5 July 2013, replaced by the M4 Coupe starting with the 2015 model year,[1][2] but the M3 name will remain in use for the saloon version.
Based on the 1986 model year E30 3-Series, the E30 M3 used the BMW S14 engine.

In contrast to later M3 iterations, the E30 M3 was campaigned by BMW as well as other racing teams including Prodrive and AC Schnitzer in many forms of motor sport including rallying and racing. The latter included campaigns in the World Touring Car Championship, Deutsche Tourenwagen Meisterschaft, British Touring Car Championship, Italian Touring Car Championship, French Touring Car Championship and the Australian Touring Car Championship. The production of the E30 road car was to homologate the M3 for Group A Touring Car racing. It was to compete with various models including the “2.3-16V” variant of the Mercedes-Benz W201 190E that was introduced in 1983. In its final years of competition, the 2.5-litre S14 engine in full race trim was capable of producing over 250 hp (190 kW).

The E30 M3 road car[edit]
The road car engine produced 195 PS (143 kW) with a catalytic converter and 215 PS (158 kW) without a catalytic converter for the later version.

The “Evolution” model (also called “EVO2”) produced up to 220 PS (160 kW). Other Evolution model changes included larger wheels (16 X 7.5 inches), thinner rear and side window glass, a lighter bootlid, a deeper front spoiler and additional rear spoiler. It was only available in coupe and convertible bodies, no saloon option was available.[6]

Later the “Sport Evolution” model production run of 600 (sometimes referred as “EVO3”) increased engine displacement to 2.5 L and produced 238 PS (175 kW). Sport Evolution models have enlarged front bumper openings and an adjustable multi-position front splitter and rear wing. Brake cooling ducts were installed in place of front foglights. An additional 786 convertibles were also produced.
